Reliable masonry drilling with Milwaukee MX4

Practical benefits

Solid four cutter carbide head: The 4-cutter tip prevents jamming whenever you strike rebar in heavy-duty reinforced concrete applications.
Fast and clean dust extraction: The 4-flute design rapidly channels dust out of deep holes to maintain drilling speed and reduce heat.
Extra reach for deep holes: With an 800 mm working length and SDS-Max shank, you can easily drill through thick structural walls.

In a nutshell

The right choise for

With the Milwaukee SDS-Max MX4 hammer drill bit, you can drill deep, precise holes through concrete, reinforced concrete, and masonry. Its solid 4-cutter carbide head prevents jamming when hitting steel rebar, keeping your work moving without interruption. The 4-flute spiral geometry rapidly clears drilling dust out of the hole to minimize friction and sustain drilling speed. Featuring a 25 mm diameter, an 800 mm working length, and a 920 mm overall length, this SDS-Max bit provides the reach and durability needed for heavy-duty cable, pipe, and structural wall pass-through installations.

Overall length: 920 mm
Shank type: SDS-max
Material (drill bit): Carbide tip

Cutting length: 800 mm

Product description

Large carbide tip with patented rebar chamfers. Ensures lower vibration and optimised drilling performance when hitting reinforced steel equalling longer life time.
Especially developed robust head geometry with optimum 4 x 90° symmetry of carbide tip. Reduces jamming up on hitting reinforcing steel.
Centering point with 130° point angle. Easy spot drilling with pinpoint accuracy and ensures optimum guidance during drilling.
Big, robust secondary cutter with dynamic, curved cutting edge. Supports the primary cutter for faster drilling.
Shorter spiral windings. For faster transport of drilling dust from the head to the flute = Less wear and heat build up at the tip.
Innovative, unique carbide tip. With more carbide on all diameters and extra carbide on Ø >32 mm.
Wear mark on both sides of primary cutter. Guarantees diameter accuracy i.e. for anchor fittings. Life time indicator in warranty cases.
Patented reinforced flute geometry. Lower vibrations for smoother drilling. Stronger flute means less breakages. Better transfer of hammer energy to the tip.
Deep flute shoulders. High volume dust removal for optimum drilling speed less wear and heat build up.
Low vibration drilling performance. Comfortable drilling ensures less stress for man and machine.
Special surface treatment. Shot blasting provides a smooth surface and densifies the surface structure and makes the bit more wear resistant.
PGM conformity. Guarantees precise holes for anchor fitting over the entire life time of the drill bit.
